Whether is it about the organization, processes, or tools, any project or transformation program that deeply disrupts a team’s way of working, triggers challenges such as a lack of understanding, fear, reluctance or uncertainty. Professional change management aims at tackling such human challenges, and is a must-have to increase chances of project or program success. To efficiently change people’s ways of working, it is key to concurrently ensure understanding and buy-in, competency development, alignment of management systems and role modelling with a solid stakeholder management, communication, and training concept.
